PROBLEM TO BE SOLVED: To resolve vignetting, luminance shading, and color shading in a peripheral pixel due to inclined incident light by providing a microlens for a solid-state imaging element which can efficiently deflect light incident from an oblique direction, so that the light may be introduced at right angles into a light receiving plane; and to provide its manufacturing method. SOLUTION: The microlens 100 for a solid-state imaging element consists of microlenses 21 so arranged as to correspond to individual pixels formed on the light receiving plane side of a solid-state imaging element. Out of the microlenses 21 arranged radially from the center of the light receiving plane, those 21b and 21c on the periphery side of the light receiving plane are formed in a curved contour which becomes gradually narrower radially in top view while becoming lower radially in cross-sectional view.
